Claims (14)
- Procédé destiné à améliorer la conduction électrique, comprenant :
le revêtement d'un corps composite avec une couche adhésive comprenant un matériau conducteur, dans lequel un composant métallique est relié électriquement au matériau conducteur de la couche adhésive, le composant métallique étant couplé au corps composite. - Procédé selon la revendication 1, dans lequel le corps composite est une structure d'un aéronef ou de tout autre véhicule composé de matériaux composites formés de polymères renforcés de fibres de carbone (CFRP), le composant métallique est une pièce de fixation, et le composant métallique relié électriquement au matériau conducteur de la couche adhésive fait partie d'un système de protection contre la foudre, d'un système de gestion des effets électromagnétiques (EME), ou d'un système de mise à la terre.
- Procédé selon une quelconque des revendications 1 ou 2, dans lequel le composant métallique comprend un manchon, une rondelle ou un autre élément positionné au niveau d'une interface entre une pièce de fixation et le corps composite.
- Procédé selon une quelconque des revendications 1 à 3, dans lequel la couche adhésive comprend au moins un élément parmi une encre électriquement conductrice ou une peinture électriquement conductrice.
- Procédé selon la revendication 4, dans lequel l'encre ou la peinture électriquement conductrice est composé d'une pluralité de particules comportant au moins un élément parmi du cuivre ou de l'argent dans une formulation comportant des agents de trempage à basse température.
- Procédé selon la revendication 5, dans lequel l'encre ou la peinture électriquement conductrice comporte du titane, le titane favorise l'adhésion aux fibres de carbone du corps composite en convertissant une mince couche de surface des fibres de carbone en carbure de titane (TiC), et les particules forment une couche adhérente plus épaisse sur le dessus du TiC.
- Procédé selon une quelconque des revendications 4 à 6, dans lequel l'encre ou la peinture électriquement conductrice est appliquée sur le corps composite en utilisant au moins une méthode parmi la sérigraphie, l'impression au jet d'encre, la gravure en creux, le transfert de film sec, la métallisation ou le placage.
- Procédé selon une quelconque des revendications 1 à 7, comprenant en outre le durcissement de la couche adhésive revêtant le corps composite à une température qui n'affecte pas de manière défavorable le corps composite.
- Procédé selon la revendication 8, dans lequel la température est comprise entre environ 100° C et environ 200° C.
- Procédé selon une quelconque des revendications 8 ou 9, dans lequel l'étape de revêtement comprend en outre le dépôt de la couche adhésive à l'intérieur d'un orifice dans le corps composite et l'étape de durcissement comprend en outre la réalisation du durcissement in-situ de la couche adhésive déposée à l'intérieur de l'orifice.
- Procédé selon la revendication 10, dans lequel le durcissement in-situ de la couche adhésive est réalisé par au moins une méthode parmi la cuisson, le chauffage radiant au flash, ou le chauffage au laser.
- Procédé selon la revendication 10, dans lequel le durcissement in-situ de la couche adhésive est réalisé par un chauffage par induction électrique lorsque le composant métallique est inséré dans l'orifice.
- Dispositif destiné à améliorer la conduction électrique, comprenant un corps composite, un matériau conducteur et un composant métallique fabriqué selon une quelconque des revendications 1 à 12.
- Aéronef avec une conduction électrique améliorée, comprenant un dispositif selon la revendication 13.
